Abstract

In this study, N-hydroxymethyl
acrylamide (HMAm) monomer was mixed with Na-Montmorillonite (Na-MT) in
different ratio. The mixture was polymerized in the presence of benzoyl
peroxide (Bz₂O₂) with in-situ radical polymerization to
prepare poly(N-hydroxymethyl acrylamide) (PHMAm)/Na-Montmorillonite (Na-MT) composites.
Purified Na-MT, and also produced composites with different ratio were characterized
with Fourier transform infrared (FTIR)
spectroscopy, X-ray diffraction (XRD), scanning electron microscopy
(SEM), thermal analysis (TGA/DTA) techniques. The moisture retention,
water uptake, adsorptive properties of composites was also researched. The XRD pattern demonstrated that Na-MT layers intercalated into the PHMAm matrix. The composites displayed
much better thermal stability than
the pure polymer.

Keywords

Composite, clay, poly(N-hydroxymethyl acrylamide), benzoyl peroxide
